The Schedule referred to in these Letters k'atent and making part of the same.

To all whom it may concern 7 Be it knowntlmt LBEXJAMIN Bansv, of Time,

in the county otlike and" State of illinois,jliave invented anew andvalnableImprovement in Fanning.-

Mills; and I do herebydeclare that the fiillowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification reference marked Figure l of the drawingis a representation of a side elevation of said'inill.

i Figure 2 is a vertical longitudinal section.

Figure 3is a vertical transverse Section. Myinventiou'relates to ccrtaiuimprovements in The ilnprl-ivements have reference to the general construction of a: ianning-inill to secure the proper result. f l V In the accompanying drawing- A represents the frame of the-mill. 4, 15 represents. the "hopper, cimnnunicating with a iongitndinally-vibrating riddle, C. Y 1) represents thellin, situated behind the riddle,

E is the driving-wheel, from which motion is given to the fan by means 'ot a belt, 0, which passes h oni the \\'l ieel}E around the pinion ll, secured to one end of the fan-shaft- Tlieother end of said shaft-holds.

an eccentric wheel; Eli-pin which vibratory motion is conveyed-to the riddle tlnj'ough the arms fand g, shalt y, and adjustable hinge G.

G represents a key flirlsecnring said hingeto the shaft'gatany position to which it may he adj ustcd.

-The objectof: saidhingc, it will be observed, is to regulate the proper hcight and incline of the riddle. D represents a cylindrical fan-case, which commuj nicates with the lltllllGSOllS to admit the current of Man, as set in motion hythe fan, to the agitated grainfi l H is a verticalspouti situatedbetwccn the sides of theshaft'd being journaled transversely in the frame 1 the f time A, and also between the fan-case and riddle.. h is an inlet to, and h an outlet from, said spout, for the admission and escape ofgrain, respectively.

I is a door, designed to regulate the size of the inlet it, and is provided with an operating-handle, 1', outside the spout. I

J is the cheat-box, inclined, as shown in fig. 2, toward the rear end of the machine, where it is provided with a door, J

The forward end of the cheat-box communicates with the upper endin'throat of p the spout H.

The fan and cheat-boxes have double walls on either side, forming airpassages, K, which open into the respective boxes at k and l.

fianningenillsfor cleaning .whcatzuid other grain, in

which the cheat and light. oii'al are removed by means of a rapidcurrent of aiiydirected into the'graiu while" *it is being shaken or conveyed through the several proper apartments of the machine.

The upper half of the fan-box, with the hopper, may be taken off.

The operation of this machine is as follows:

The grain escaping from the hopper to the riddle is agitatcd, and, passing through the screen, comesin-- contact with the current of air from the fan-box, 'which releases. the light particles of cheat. The grain. then passes from the shoeinto the suction-spout H,

where itinects an upward current of air rushinginto theair-passages and. fan-case to .supply the vacuum created by the fan.

This-upward current carries the cheat and lighter particles with it and deposits them in the cheat-bog, fl'om which they are taken through the door J, while In testimony that I claim the above I have hereuna to subscribed my name in the presence of two wit- \Vitnesses: BENJAMIN BARN BY;
